I have wrote an app in vb to run at 30 min intervals on a HTC 6500 with WM6.
I have used the CeRunAppAtTime function to close the app and reopen in 30 mins time, this works fine up until the device goes into suspend mode. However once you press the power button it runs the app (even though the time has passed).
I have tried SetSystemPowerState to turn back on if in suspend mode, e.g.
SetSystemPowerState(Nothing, POWER_STATE_ON, POWER_FORCE)
However I'm struggling to understand where i need to call the SetSystemPowerState in my code (as shown below). Any help with this would be much appreciated as its driving me bonkers!!!
Source Code:
Dim FullAppName As String = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase
Dim AppPathOnly As String = System.IO.Path.GetDirectoryName(FullAppName)
Dim NewDate As Date
Dim wakeuptime As SYSTEMTIME
Public Structure SYSTEMTIME
Dim wYear As Short
Dim wMonth As Short
Dim wDayOfWeek As Short
Dim wDay As Short
Dim wHour As Short
Dim wMinute As Short
Dim wSecond As Short
Dim wMilliseconds As Short
End Structure
Private Sub scheduleapp()
NewDate = Now
'take the current time and date and add some hours, minutes, and seconds
NewDate = DateAdd(DateInterval.Hour, 0, NewDate)
NewDate = DateAdd(DateInterval.Minute, 30, NewDate)
NewDate = DateAdd(DateInterval.Second, 0, NewDate)
'populate systemtime structure with our new date
With wakeuptime
.wDay = NewDate.Day
.wDayOfWeek = NewDate.DayOfWeek
.wHour = NewDate.Hour
.wMilliseconds = NewDate.Millisecond
.wMinute = NewDate.Minute
.wMonth = NewDate.Month
.wSecond = NewDate.Second
.wYear = NewDate.Year
End With
If CeRunAppAtTime(FullAppName, wakeuptime) Then
MessageBox.Show("Set to wakeup in 30 mins")
Me.Timer1.Interval = txtSetTimedWakeUp.Text
Me.Timer1.Enabled = True
Application.Exit()
Else
MessageBox.Show("Call to CeRunAppAtTime failed")
End If
End Sub
Private Sub cancelschedule()
'Make a call to cancel the scheduled app
Dim cancelapp As Boolean = CeRunAppAtTime(FullAppName, Nothing)
End Sub

Hi!
I'm relativ new to RegExp and writing patterns. I wan't to write the pattern for (danish) dates between 01-01-1970 and 31-12-2099. How do I do that? I'm a little confused with the | op. I think. My best try is:
string strPattern = @"^([0-2][1-9]|[3][0-1]){1}-{1}([0-1][1-2]){1}-{1}([1][9][7-9][0-9]|[2][0][0-9][0-9]){1}$";
Where (...){1} should be exactly 1 of the exclusive choices in (...)
It seems to work validating it here: http://www.sweeting.org/mark/html/revalid.php#calc[^]
But in c# it do not work! Whay is that?
Regex rx = new Regex(strPattern);
rx.IsMatch(test) - seems to be false most of the time!
I can't figure it out - help!

Should the - be enclosed in \\ like: \-\ ?

the regex works fine in Expresso, and since Expresso uses .net regex engine, it should work fine, Maybe the problem is in an another part of you code?
01-01-1970 <- Validates
31-12-2099 <- Validates
31-12-2100 <- Doesn't validate
01-01-1969 <- Doesn't validate

Thanx' I'll check it out...

{1} is entirely redundant. Anything without a specifier is required exactly once. Also, a character class with one element is just extra typing, so [1][9] should just be 19. The only obvious problem I see is the month section only gets 01, 02, 11, and 12. I would try this:
^([0-2][1-9]|3[0-1])-(0[1-9]|1[0-2])-(19[7-9][0-9]|20[0-9][0-9])$
|
|

Also this works:
private readonly string STR_DDMMYYYY_PATTERN = @"^([0][1-9]|[1-2][0-9]|[3][0-1])-([0][1-9]|[1][0-2])-([1][9][7-9][0-9]|[2][0][0-9][0-9])$";
I figured the {1} problem out also. Seems that the validator-site is OK with dealing with apparently redundant chars - but class Regex are not?
So now this is OK:
Regex regexpDDMMYYYY = new Regex(STR_DDMMYYYY_PATTERN);
bool bIsValid = regexpDDMMYYYY.IsMatch(tbGeneral.Text);
if (bIsValid)
{
...
etc.
I'll test the [1][9] replacement also.
Thanx' again.

A while back, I wrote a blog entry[^] on a general purpose regular expression date validator that you might want to take a look at. The code should give you some ideas, especially as it can show you why regular expressions for dates aren't enough on their own.

Hi guys,
I am writing a C# app with Visual studio 2008 professional and .NET 3.5 on an XP SP2 box
I build an MSI installer and install it on a target machine (XP or Vista, same problem)
The install specifies 'All users'
I can start the app from other accounts than the one who installed it, but if the password changes, I cannot start it anymore
(get a message saying 'XYZ encountered a problem and must close... Send a report to Microsoft)
Does someone have an idea of what I am doing wrong?
Thenks

I am looking to lock my usb pen drive. It should ask for password when i try to open the file in the usb pen drive. Is there any way I can do this using vb.net or c#.

I do not know a programmatic way to do what you want. Someone else may come along who does, but in case not:
1) TrueCrypt has a tutorial here[^] on how to do it with their software, which I believe is free.
2) Zip the confidential data in a password protected *.zip file. There are several free Zip Libraries for .NET. (google)
3) Get a U3 enabled drive such as this[^] one which comes with security enabled. The link is a UK one, but it is the drive that you should look at.
